Application November 15, 1943, Serial No. 510,312

2 Claims. (01. 285-90) provide a highly improved adaptor at one end of thetube or hose constructed of plastic material and having improved. tight locking means for gripping the tube. a r

. A further object of thepr'esent invention is to provide an adaptor of ,the character described having an annular groove to receive one end of the flexible tube welded within the groove, thereby eliminating show or sign of welding.

Another object, of this invention isto provide an adaptor of the character described which may be readily assembled, and the assembled parts welded or fused together, said adaptor being provided with a disc of elastic material formed with an opening to receive faucets of various sizes. i

Yet another object of. this invention is to provide a strong, rugged and durable'spray device of the character described, which shall be relatively inexpensive to manufacture, attractive in appearance, easy to assemble and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described,

and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention,

Fig. 1 is a perspective view of a spray device of the character described, connected to a faucet, with parts broken away and in cross-section;

Fig. 2 is an axial, cross-sectional view of the improved. adaptor part of the spray device;

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig; 2;

Fig. 4 is a cross-sectional-view taken on line 4--4 of Fig. 2;

' Fig. 5 is a view similar to Fig. 2, but illustrating a modified construction; and

Fig. 6 is a cross-sectional view taken on line 6-6 of Fig. 5.

Referring now in detail to the drawing, Ill designates a spray device embodying the invention. The same comprises generally of a flexible tube or hose II to one end of which is connected a spray or shower head l2, and to the other end of which is connected an adaptor H3. The tube l I may be made of rubber, or vinyl chloride plastic material, orof any other suitable flexible and elastic material.

The adaptor l3 comprises a funnel shaped member l6 preferably made of plastic material such as cellulose acetate or butyrate plastic and connected to the tube II in the manner hereinafter described. Member I6 comprises .a tapering, substantially conical or semi-spherical portion I! open at the top, and formed at its bottom end with a tubular extension [8.

At the junction of the tubular portion I8 with the portion I1 is a downwardly extending skirted portion I9 concentric with tube 18 and spaced therefrom, forming an annular downwardly opening groove ,20 at the base of tube l8. At

the upper end of portion llis an outwardly ex tending annular flange 22 formed in its upper surface with an annular "upwardly opening groove 23. Extending upwardly from the upper edge 24 of portion I! are a plurality of angularly spaced upwardly extending projections or "teats 26 for the purpose hereinafter appearing,

disposed inwardly of the groove 2 On the upper end of member I6 is a disc 28 made of rubber or plastic material such as vinyl chloride or the like compressible, elastic material. Disc 28 is formed with a central opening 29 to receive faucets of various sizes. The opening 29 is preferably conical as shown at 30, decreasing in diameter toward the top. Disc 28 is held or retained on member I 6 by a retainer or cover member 32. Member 32 comprises a cylindrical wall or portion 33 and a top annular horizontal flange 34 forming a central opening 35 substantially similar to the inner diameter at the upper end of member IS. The lower edge 33a of wall 33 is received in the groove 23 as shown in Fig. 2 of the drawing. It ispreferably fused with or welded to member l6 by dipping the edge portion 33a, of member 32 in acetone and also by applying acetone to the bottom of the groove 23 and then pressing said edge portion into the groove, the acetone serving to seal or fuse or weld the parts together.

It will be noted that downward pressure on are dipped in acetone before. pressing the tubular i a portion l8 into the hose.

Means is provided to make a lock tight grip:

for the tube ll so that it will not come oil the adaptor. To this end there is provided an annular ring 40 which may likewise be made of plastic material such as cellulose acetate or butyrate,

plastic. The ring 40 has a cylindrical inner surface having a diameter substantially equal to the outer diameter of tubular portion I8. It has a conical outer surface 42 decreasing'in diameter toward its lower end. The ring 40 is fixed to the tubular portion I8 below the skirt l9 and above the lower edge of said tubular portion by welding it to said tubular portion by means of acetone,- as described above.

It W111 be noted that the tube u passes over the ring 40 and is gripped thereby providing'a lock tight grip to prevent release of the tube. The annular grooves eliminate any show or sign of welding. The lock tight grip eliminating ferrules which are usually used to clamp the hose to the adaptor in prior devices. V

The shower head l2 may be of any suitable constructionand is preferably likewise made of plastic material and is connected to the opposite end of the hose l l in the same way as member ,l 6 is connected to said hose.

In Figs. 5 and 6 there is shown an adaptor I3 provided with amodified form of disc. In-fact as-shown in Fig. 5 the adaptor contains a pair of superposed discs 50 and 5|. The discs 50, 5| are of half the thickness of disc 28. The top disc 50 is formed with a central opening 50a and the bottom disc 5| is formed with a central opening 5Ia. The opening 5la is of larger diameter than the opening 50a. The discs are clamped together by the retainer 32. The top disc 50 will engage smaller faucets, but if the device is attached to a larger faucet it will be gripped by both discs 50, 5|. With such construction, there is eliminated the necessity for forming conical opening 30 such as in disc 28, which presents operational difiiculties at th present time.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which .is well adapted to meet. the conditions .of practical use.

various possible embodiments might be made of the above invention, and as various .Xchanges might be made in the embodiments above set forth, it is to be understood that all Lmatter herein set forth or shown in the accompanying drawing, is to be interpreted as illustr'ative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

lpAn adaptor, comprising a funnel like member formed with anannular groove at its large open end, a disc on said large end, saiddisc being formed with a central opening, the outer diameter of said disc being less than {the diameter of said groove and a retainer for retaining said disc on said member, said retainer having a cylindrical wall surrounding the outer edgeof said disc,- one end edge of said. cylindrical Wall being received in said annular groove and f xed therein, and said retainer having a top flange engaging the top of said disc to retain the same on the large end of said .member.

' 2. An adaptor, comprisinga funnel like'rnember formed with anannular groove at its large open end, a disc on said large end, said disc being formed with a central opening, the outer diameter of said disc being less than the diameter of said groove, and a retainer for retaining said disc on said member, said retainer having a cylindrical wall surrounding the outer edge of said disc, one end edge of said cylindrical-wall being received in said annular groove and fixed therein, and said retainer having a top flange engaging the top of said disc to retain the same on'the large end of said member, said disc being made of compressible, resilient material, and said member being formed with integral projections pressed into said disc'to aid ,in retaining the latter against rotation.
